Keep in mind that the K3/Mini-0 controls what is happening at the K3. So the question is what happens at the shack using the speaker volume knob there. When changing the speaker volume at the K3/0-mini you’re also changing the volume of whatever is happening at the shack’s speaker output. Thus, in my case, if the powered speakers at the shack are left on and I change the volume level on the K3/0-mini, it is also changing the volume level going to the powered speakers in the shack. IF LINE OUT is a variable in the CONFIG menu, whatever you change on the K3/0-Mini when in Config mode for Line Out will control the Line Level going out at the K3. As I understand it, setting LIN OUT includes both volume level and the control of volume. Tapping ‘1’ will change LIN Out to = PHOnES, and the audio level is controlled by the AF/SUB gain controls. In addition, you would need to set SPKR + PH to yES so that audio is still provided to the Speaker when Phones is in use. That way, you don’t have to change the audio output at the K3 when using it either by the K3/0-Mini or directly in the shack. However, this also means that when you’re at the remote site, the K3 Speaker will be active when operating remotely. Presumably you could connect your RR Box to this connection instead of speakers and this may indeed provide what you’re looking for. What you’ll need to determine is whether the provided audio Line Level output will be sufficient to drive the K3/0-Mini internal speaker. I don’t know if the Remote Rig audio will compensate for different levels provided by the the K3 speaker jack versus the K3 Line Out jack. It seems to me that the simplest solution to your concerns is simply insert a splitter in the K3 speaker out jack and share the audio with external speakers at the shack along with the Remote Rig box. With the arrangement, there is nothing to plug/unplug when you’re back in the ham shack and the process for speaker audio level control remains unchanged.

[Elecraft] K3 Line Out audio input to Remote Rig RRC 1258 MKII
I have a Remote K3 using K3 Mini at my home shack. The audio output from the remote K3 is taken from the SPKRS jack and fed to the Audio IN jack on the RR box. I have often wondered about taking audio from the LINE OUT jack and feed that audio to the RR Box. Doing this would allow me to use the radio when I am at the remote site without having to reach behind the radio in the rack and UNPLUG the audio cable so I can hear the speaker. Several times I have left the site with out plugging the audio cable back in which renders the remote useless when I arrive home. I know the level of the LINE OUT is variable in the CONFIG menu. Does the AF control on the K3 Mini also control the level of the audio to the Mini speakers --- that audio would be fed to the remote RR box from the LINE OUT jack on the remote K3.?

[Elecraft] K3- Line Out Audio
I'm going to second Peter's request, but let me explain it in a different manner. I'll use the terms "Rx audio" to mean the audio from the receivers, and the "Tx Mon" to mean the audio that is being transmitted.; you get a constant audio level output regardless of your AF setting. Currently, the Line Out audio level is adjusted in the Config menu. For recording purposes, IMHO, it works correctly. If you want to record just the receive audio, it is fine. When you want to record the actual contest, though, the receive audio alone isn't enough; you also need the Tx Mon audio. The Tx Mon audio that is mixed into the Line Out audio is varied by the Tx Mon level control on the front panel. If you turn the Mon control fully counterclockwise, you have no Mon audio in your headset and no Mon audio in the recording. Why is this important? As an SO2R operator, I use the Tx Mon audio for two things: make sure I'm not sending gibberish, and as an audio cue that a specific radio is done transmitting. The Mon level is set so that I can barely hear it in the headphone; many SO2R ops use the Mon in just that manner, as does PC2A. If you adjust the Mon gain in that manner, the Tx Mon audio disappears from the recording. In addition, many ops route the mike audio through the soundcard so that they can do on-the-fly recording. Many soundcards introduce enough latency into the process that listening to yourself through the delay is very fatiguing; the easy solution is to turn the Mon level so that you don't hear it. When you do that, the Mon audio disappears from the recording. What we'd like to see is the transmitted audio, be it from cw sidetone or digital signal or ssb audio, to be mixed into the Line Out audio at a level that is not changed when the Mon control is adjusted. The transmitted audio level should be adjusted in step as part of the Line Out Config menu selection. With the new recording needs of CQWW, this should be implemented.

[Elecraft] K3: LINE OUT weirdness
Earlier I reported a problem where the LINE OUT level setting had no effect on the actual output level, but the front panel volume control did. Well, I downloaded and installed latest firmware, which was different from what I downloaded just a few days ago. That fixed both symptoms, except: * While the front panel volume can now be reduced to nothing while the line output level is good and controlled by the menu setting, if I increase the front panel volume above a certain level, it starts to cause increased levels in the line output, as evidenced by the connected laptop's waterfall. * The increased noise is not uniform across the audio spectrum, but appears amplitude modulated with a sine wave so that about two noise maxima are found per 500 Hz. Further increase in speaker volume results in stronger "banding" of the noise. * With external speakers plugged in, the same happens, but disconnecting one speaker leads to a marked reduction of the banding. * When no speaker is connected (uncorded plug in speaker jack), there is no banding. Note that I have disabled the built-in microphone in the connected computer, and the speaker volume - related waterfall noise increase is not diminished when I muffle the radio speaker by putting a book over it; nor do I see any reaction when I whistle into the laptop's microphone. My best guess at this time is that the added noise is caused either inductively by speaker current affecting the radio's isolation transformers, or the speaker amp current draw causing a variation in supply voltage, maybe only in a local part of the radio. I have not yet checked the power supply for hum etc. There might also be some grounding deficiency, as I have not done any bonding between the boxes. The waterfall shows a couple of constant audio tones of moderated strength, located at about 1185 Hz and about 2370 Hz (if I can trust the calibration within MMVARI). Years ago I did the hardware mod's relating to the speaker amp, but I haven't checked for recent mod's. Any comments or suggestions are welcome!

[Elecraft] K3 line out
Dear Jim: Something is screwy. I run the same sound card, but usually run around level 10 on the k3 to put the input in the middle of the Tascam input level knob range. Make sure you are using the right input jack on the Tascam, and the line out on the k3. When I used an internal sound card on a laptop with a too-sensitive mic input, I used a cheap Radio Shack headphone cable with an inline volume control. I ran that on EME for years and it worked like a charm. 73, Eric WD6DBM Sent from the metering jack on my Heathkit Twoer __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] [K3] Line Out level
Is there any chance of getting the K3's line out level lowered? Even when set to it's lowest level of 1, it puts out a bit too much audio for my TASCAM US-100 external sound card. The TASCAM has an external input level control and even with it all the way down, the K3 puts out too much audio for all the sound card apps I use (Digipan, MMTTY, FLDIGI, etc). If set to zero, then there's no output at all. The output level for #1 in the menu should be about half or maybe even a quarter of what it is now. That would also allow the various Windows mixers a lot better control over the soundcard input level too.

Re: [Elecraft] K3 line out - Stereo vs Mono
Paul, Now that I have an answer to that I'll go with the recommended K3 RX <--> PC TX and K3 <--> TX to PC RX (solving the exchange of audio) I would not bother connecting the RASCAL's receive side. Simply use the stereo audio cable between the K3 "Line Out" and the PC "Line IN". Reserve the RASCAL for the FSK/PTT connection to the K3's AUX. Can I use the RCA PTT IN jack on the back of the rig to key it for RTTY, PSK, JT65, etc.? I prefer FSK to AFSK and hence would rather use PTT instead of VOX. Sure you can. However, if you already have the RASCAL and it provides a PTT connection to the AUX jack, why not use it for PTT even with PSK/JT65A/etc.? I assume the RASCAL is an FSK interface with RX audio from Line Out and FSK/PTT to AUX (DB15HD). If, on the other hand, RASCAL is a simple passive audio box with a serial control port, connect the PTT line from it to the RCA PTT jack and use two stereo audio cables from the K3 to the computer sound card (you don't want to cascade transformers - it's unnecessary and prone to distortion given the quality of the transformers in some external boxes). 73, ...

Re: [Elecraft] K3 line out - Stereo vs Mono
Paul, The short answer is the warnings do not apply to Line Out. Line Out is always stereo but both right and left are transformer coupled (you don't need the Rascal) and the primaries of both transformers contain resistors that would limit current from the DAC to a safe level even of the output of the transformer were shorted. I refer you to the K3 Schematic package on the Elecraft web site. 73, ...

I have another question that's somewhat related to my original post. I know it has been discussed many times over; that one should avoid using a mono plug in the SPKRS jack. What I'd like to know though is this: Would it be OK to use a mono plug in either front panel PHONES output, or rear panel PHONE or LINE output without fear of blowing something up? Manual says it should be fine, but just want to get confirmation beforehand that this is OK to do.

On the Mac OS X side, cocoaModem has two independent receive channels in the "wideband RTTY" and the "dual RTTY" interfaces. There are two identical sets of user interfaces in a single window -- this gets rid of the "window focus" problem of running multiple copies of a software modem. There are two cross ellipses, independent mark and space tones, baud rate, and filter settings -- you can even run 75 baud and Mark-only on one decoder, while running 45.45 baud and Mark/Space decoding on the other. In the case of "wideband RTTY," there are independent waterfalls. Dual RTTY decode has been in practice in some time now. In the old days, it was done with multiple TU -- this is one of the reasons why normally sane people have multiple HAL ST-8000 in the shack. Just like other modes, having concurrent receive capability on on both the DX and a split pile reduces "doubling." Using multiple TU back then required manually scanning the pileup using the VFO knob. If you have a waterfall that is watching the pile, you can pretty much pinpoint the DX's QSX by watching where a signal appears in the pileup waterfall right after the DX finishes sending his exchange. A software modem that is capable of agile transmit can then pounce on that QSX (or find the next hole in the direction the DX is tuning). It used to be like shooting fish in a barrel for people with two RTTY decoders and agile receive (e.g., waterfall tuning) to work the split RTTY pileups. Just ask RTTY DXers who have been using cocoaModem's "wideband RTTY" interface. But more people have that capability today (what with the Flex-5000 and the LP-PAN), to the point that if you don't have dual decoding and agile tuning capability, you are now at a distinct disadvantage. Of course you need a sound card that has two or more inputs (or a digital interface like the microKeyer/digiKeyer). Some of the cheaper digital interfaces are only wired for a single input channel, even when the codec is a stereo one. 73 Chen, W7AY __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

The hardware setup to use both receivers in RTTY is simple, and no different from what you use with a single receiver - a single stereo cable from the K3's LINE OUT to the sound card's LINE IN for receive, a single mono (or stereo) cable from the sound card's LINE OUT to the K3's LINE IN for AFSK transmit, and use RTS on the radio control port for PTT. Or, if you prefer FSK, replace the AFSK transmit cable with FSK and PTT keying circuits to the AUX input. There is no need for a second sound card, no need to cut cables, no need to use a mixer to adjust balance. You set up one copy of MMTTY to receive using only the left channel of a single sound card, and a separate copy of MMTTY to receive using only the right channel of the same sound card. The two operate entirely independently. One decodes the signal from the main receiver, the other one from the sub receiver. If you only want to copy one signal, just don't look at the output from the other copy of MMTTY, or if you find it distracting, just turn SUB off and/or close down the second copy of MMTTY. From N1MM Logger, you can open two Entry windows, one for each VFO, and open a separate Digital Interface window from each Entry window, with separate copies of MMTTY each configured to use the appropriate channel of the sound card. You can receive on both receivers at once, and choose which one to transmit to with the "\" key. Or, if you only want to use one VFO, just close down the second Entry window. 73, Rich VE3KI NF4L wrote: > All that strikes me as a kludge, but I certainly don't have a better > solution. :-( > __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] [K3] Line out, speakers, and L-mix-R settings...
I'm not suggesting mixing signals, in fact I'm trying to arrive at a method of conveniently eliminating one of them. I just looked into MMTTY and saw (for the first time) the ability to select mono, left, or right.

Re: [Elecraft] [K3] Line out, speakers, and L-mix-R settings...
Joe, if you mean stand alone MMTTY, I don't understand. I wouldn't want to copy copy both signals. Each copy of MMTTY could use a different sound card (given 2 sound cards) but still no way to direct sound by channel. I suppose the Windoze mixer could be used to set the balance. Or cut a wire in the audio cable. All that strikes me as a kludge, but I certainly don't have a better solution. :-( Mike NF4L On 11/27/2010 8:14 AM, Joe Subich, W4TV wrote: I don't have a sub rx, so it's never been a problem for me, but I'm >>> thinking of adding one.

Re: [Elecraft] [K3] Line out, speakers, and L-mix-R settings...
Mike, Thanks for pointing that out - I had completely forgotten about that option. I guess it's time I printed out a new copy of the manual! Of course, that changes the answer to James' question #2; if you want the LINE output to be a clone of the headphones output, set CONFIG:LIN OUT to =PHONES. With CONFIG:LIN OUT =PHONES, when the subRX is off, the main RX is in both channels. This setting seems tailor-made for James' situation (listening to speakers through a sound card). For digital modes, as Joe has pointed out, when SUB is on, you use the two channels to feed two independent copies of MMTTY (or other software). You do not want any mixing of the two signals. Also, you do not want the volume control to affect the audio level going into the decoder. If you use the audio pitch as a tuning aid, you want the ability to turn the audio down or to change the balance between the two channels without interrupting the ongoing decoding of both signals. When SUB is off, you only use (or need) one channel in the sound card. The right channel waterfall just goes black when the sub RX is off. You can use two different decoding algorithms on a single signal by running two (or more) independent decoding programs (e.g. two or more separate copies of MMTTY using different profiles) from a single channel in the sound card. 73, Rich VE3KI NF4L wrote: > Re: point #2. > > I don't have a sub rx, so it's never been a problem for me, but I'm thinking > of > adding one.

[Elecraft] [K3] Line out, speakers, and L-mix-R settings...
Curious thing I noticed today; plugged in my headphones only to continue hearing monoraul audio coming out of my PC's speakers. It took me a second to realize that audio from the K3 was being piped out of the LINE OUT jack in the rear, into my PC's input, and out to the two speakers I have sitting on my desk. At first I thought it was strange that the audio I was hearing was only coming out of the left speaker rather than both. I checked the manual and after a few minutes of reading realized that under normal situations, activating the SUB would provide the right channel. I then started playing around a bit more, and figured I'd post this question to the group just to make sure I understand how these functions work properly. My experimentation led me to the SPKRS settings which was currently set at 1. With the SUB off, I changed the speaker setting to 2 but no change; audio was still being heard on the left speaker and not the right. Am I then correct in my assumption that the speakers setting has no bearing on the actual number of channels being output from the LINE OUT jack? This brings me to my second question - is there a way to get both L and R channel audio output to the LINE OUT jack just from the main receiver without the SUB being activated? My last question, does the SPEAKERS setting only affect the SPKR OUT jack on the rear panel? According to the manual, leaving it at 1 will only provide one channel of audio. Would setting it to 2 provide both L&R channels to the speakers regardless of SUB activation?

Re: [Elecraft] K3 - Line Out
Dick, The line out level is fixed by the menu (CONFIG: LIN OUT), and the SPKRS or PHONES output is variable - controlled by the AF gain. They can be used simultaneously. Both/either will work into a high impedance load. I have been using the SPKRS output to drive a soundcard, a mixer or a set of amplified speakers at various times in the past with no problem - just plug it in and set the AF Gain appropriately. Remember there is a HI and a LO setting for the headphone or speaker outputs available in the menu, you may have to set it to LO. Does that meet your needs? 73, Don W3FPR Edward Dickinson, III wrote: > Using my K3 with a computer and outboard sound as well sound based programs, > both a Fixed-Level and Variable-Level (AF Gain Knob) Line Output > simultaneiously could be useful to me. > > Has a mod been developed that provides both? > > > 73, > > Dick - KA5KKT > > __ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft@mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > > > > No virus found in this incoming message. > Checked by AVG - www.avg.com > Version: 9.0.730 / Virus Database: 271.1.1/2644 - Release Date: 01/25/10 > 02:36:00 > > __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] K3 - Line Out
Using my K3 with a computer and outboard sound as well sound based programs, both a Fixed-Level and Variable-Level (AF Gain Knob) Line Output simultaneiously could be useful to me. Has a mod been developed that provides both? 73, Dick - KA5KKT __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3: Line Out level
> have found that a line output level of 50 is pretty good. Hi James. I use "Audacity" with the "Lame" MP3 plug-in to record beacons and intruders. With the PC sound card mic level at max, I need the K3 Line out at about 20 to get enough audio for Audacity. Can't hear any distortion but I'm not a hi-fi buff.

Re: [Elecraft] K3: Line Out level
James, You will not hurt the K3, but if the transformers saturate, you will get distortion. As long as the level of distortion is OK to your ears, I would judge everything to be OK. 73, Don W3FPR James Sarte wrote: > Greetings to the group! > > Quick question: I normally keep the line out set to 5 or 10; I haven't seen > the need until now to increase it.

[Elecraft] K3: Line Out level
Greetings to the group! Quick question: I normally keep the line out set to 5 or 10; I haven't seen the need until now to increase it. I recently discovered a recording utility built in to HRD, and leaving the line out level at 5 or 10 usually results in a low-volume recording. I've fiddled around with the setting and have found that a line output level of 50 is pretty good. However, I just want to make sure that doing so is safe for the K3. I've monitored the audio from the PC, and I haven't noticed any sort of overdrive condition. On the other hand, the manual states that setting the line out to anything above 10 may cause saturation of the KIO3's isolation transformers. Thoughts? Vy 73 and a Happy New Year to all!

Re: [Elecraft] K3 Line Out in Data Mode?
Dave, Thanks for the suggestion. I'm using a level of "8" ---the manual recommends no more than 10. In sideband I get a good level to the programs I mentioned. In data modes there is absolutely nothing showing on the programs displays. It's like there is absolutely no output from the Line Out on the K3. Have a good day and 73.

[Elecraft] K3 Line out level and Digikeyer
For digimodes like WSPR I use a Microham Digikeyer and set the K3 Line Out level to 10, which is the maximum recommended before the possibility of distortion is introduced. At this level I have to set the Digikeyer RX input control to max to obtain proper decoding etc and being at maximum leaves no room for further adjustment. I usually like to set in/out controls to around 50% but in this case it would mean setting the K3 Line Out to around 40 to be able to reduce the Digikeyer input by 50% So, is Line Out level 10 still the max before distortion/saturation of the output transformers occurs or is there any headroom. If 10 is still the number then fine, as the object is to provide the cleanest signal to the DigiKeyer soundcard even if the input does have to be set to max. 73 Trevor G0KTN __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Correct, microKEYER II uses the Micronas UAC2556B codec which has independent left and right attenuators for the line input. Some operating system drivers show them as independent controls while some map them as a gain/balance pair. The Micronas also has a single channel (left channel in the USB data stream) mic input. > My digiKeyer uses the Burr-Brown PCM2902; when using Core Audio, > there is no master, left nor right controls. All DigiKeyers use the TI (Burr-Brown) PCM2902 CODEC. The TI has a single dual channel audio input. There are no electronic level controls on the input (chip design). I'm not aware of on-chip attenuators on any of the TI/BB USB products. 73, ...

I have three generations of iMic, dating back from more than 5 years ago. The are the grey disk shaped ones, not the current-generation white ones. The oldest one had a 20 bit input codec, with no digital attenuator, no left, no right, no Master. The next generation is also 20 bits, but it has independent left and right attenuators (as seen from Core Audio -- I don't use Port Audio), but no master attenuator. Both of the above have 20 bit codecs in them, but uses the USB Audio Interface class and you can only see 16 bits (they don't need special drivers, but you also don't see 20 bits, HI). After that (and I believe it is true with the white bodied ones) they went to a 16 bit codec. Mine (still a gray body) only has a master level control but no individual left and right controls. If you are using Mac OS X, the easiest thing is to launch the Audio MIDI Setup utility that is in /Applications/Utilities. Audio MIDI Setup also uses Core Audio. There are three slider associated with each sound card's "volume," a Master slider, and channels 1 (left) and 2 (right). If a control is not available, it will be grayed out. The microKeyer II, for example, has the Master control grayed out but the left and right channels are independently adjustable. My digiKeyer uses the Burr-Brown PCM2902; when using Core Audio, there is no master, left nor right controls. 73 Chen, W7AY __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

We've been using TI and Micronas USB sound devices that are directly supported by the native "Windows Audio." The TI devices do not have an input mixer - sounds a lot like the iMic - but they still provide two channels of receive audio and an application can hook either channel or force the driver into mixed mono. I've used both the TI and Micronas based devices in stereo (separate left/right) for dual receive or right only (sub RX only) with MMTY, MMVARI, and MixW. Unfortunately, I see the issue with FLdigi ... it uses mixed mono with either the TI or Micronas CODECs. I can handle that by turning down the input level to the CODECS (manual gain controls) but that still does not permit dual receive. Interestingly, DM780 handles both the TS and Micronas in left channel (Main RX) only. 73, ... Joe, W4TV > -Original Message- > From: Leigh L.

Yes, so my request would be to be able to mute one of them. Using a cable to connect only left is the best solution if the rig can't mute one. It doubles the data transfer to capture both sound channels and discard one. I agree though it's not that high priority.

Re: [Elecraft] K3 LINE Out mixes KRX3 and main output?
I took a quick look at it and I think I need to capture 2x the data and discard half of it in order to get just one channel out of the sound device. So I think fixing it in hardware makes more sense...

Re: [Elecraft] K3 LINE Out mixes KRX3 and main output?
I think the right place to fix it would be in whatever software is using the captured audio - the driver is OK, but the software needs to let you select channels you want.

Re: [Elecraft] K3 LINE Out mixes KRX3 and main output?
Sorry for the confusion on the sound card side: It's a stereo input, but I don't get software control of the balance or independent gain. It's not on Windows. The Griffin iMic device specs say stereo, but the driver appears to be supporting only mono gain controls. If I go to LIN OUT menu and tapping button 1 to get =PHONES then I can use the audio gain controls to control the mix, but if I use NOR mode LIN OUT then it's always mixed. Probably easiest for me to make a cable than (a) fix the driver or (b) ask for firmware changes. Leigh/WA5ZNU > Leigh L.

That doesn't quite make sense. If your line-in is really mono, the right channel would not be connected to anything. Are you sure it's not the software you're using that's mixing the two channels together ?

[Elecraft] K3 LINE Out mixes KRX3 and main output?
Is it possible to control whether the sub rx goes to the line out or not? It seems that both main and sub rx are always going to line out; I guess they're on left/right channels? If not, I guess I need to make a cable to cut out one channel so I don't see both with my mono sound card line input.

[Elecraft] K3: Line out level in 'CONFIG:LIN OUT = PHONES' mode
Hi all, I am experimenting with recording QSOs. If I want to record my own transmission too, I have to set CONFIG: LIN OUT =PHONES. This links the line out level to the AF pot meter settings. However, the level is too low for a decent recording unless I want to blow my eardrums. When in LIN OUT = NOR mode I can set the level to 15 and I get a reasonable line out level ... Any ideas or any plans to include a "gain factor" between AF setting and line out level when in = PHONES mode ?? -- Enno, PF5X -- View this message in context: http://n2.nabble.com/K3%3A-Line-out-level-in-%27CONFIG%3ALIN-OUT-%3D-PHONES%27-mode-tp1451780p1451780.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
